Trawling is a method of fishing that involves actively dragging or pulling a trawl through the water behind one or more trawlers.

Trawling occurs mainly over sandy sediments, but areas of muddy substrate and coarser, gravely substrates are also trawled. [4] A five-year benthic trawl experiment was implemented between 2014 and 2019 with the purpose of determining the environmental impact of demersal trawling in South African waters.
Midwater (pelagic) trawling is a much "cleaner" method of fishing, in that the catch usually consists of just one species and does not physically damage the sea bottom. However, environmental groups have raised concerns that this fishing practice may be responsible for significant volumes of by-catch, particularly cetaceans (dolphins, porpoises ...
